Product Description:

1. Structure of The NUT Coke of Size is 20 – 40 mm Description：

Coke is made by high temperature metallurgical coke for blast furnace smelting, casting and gasification. Occurring in the process of coking after recovery and purification of coke oven gas is a high calorific value of fuel, is an important industrial raw material in organic synthesis.

Coke is mainly used for blast furnace ironmaking and used for copper, lead, zinc, titanium, antimony, mercury and other non-ferrous metal smelting of blast furnace, reducing agent, compound and the function of stock column frame.

Blast furnace with Coke instead of charcoal, which laid a foundation for the large-scale of modern blast furnace, is a major milestone in the history of metallurgy.

Q:Who knows what the provisions of the coke train sampling country?

Three, instrument and equipment of drying box: with automatic temperature adjusting device, can maintain the temperature of 170 DEG C and 105 a 180 a 110 C, the tray is made from galvanized sheet iron or aluminium sheet, size is about 300mm x 200mm X 20mm. The glass weighing bottles: diameter 40mm, high 25mm, and a grinding cover tightly. Dryer: inside the color of silica gel or granular anhydrous calcium chloride

Q:What is the amount of waste gas produced by a ton of coke burning

The coking coal is heated to 1000 DEG C under the condition of isolated air (high temperature carbonization)

Q:Ca3 (PO4) 2, SiO2, coke and other raw materials for the production of silica gel (SiO2? NH2O), phosphorus, phosphoric acid and CH3OH, the comprehensive utilization of raw materials in the following process

The answer is: Ca3 (PO4) 2+5C+3SiO2High temperature. 3CaSiO3+2P+5CO =; production of cement, brick or building materials such as;(3) R Si, Si and HCl reaction is the reaction of SiHCl3 with hydrogen, by the reaction of the hydrolysis of SiHCl3, IV, and the generation of hydrogen and oxygen in a certain range will explode, so it must be in contact with oxygen and anhydrous conditions,Therefore, the answer is: SiHCl3 hydrolysis, while the production of H2, mixed with O2 explosion, etc.;(4) methanol oxidation reaction, under acidic conditions, methanol in the cathode of carbon dioxide and hydrogen ions, CH3OH+H2O-6e-=CO2+6H+,The answer is: CH3OH+H2O-6e-=CO2+6H+;(5) the significance of this link in industrial production: recycling of raw materials, energy saving and emission reduction,The answer is: recycling of raw materials, energy-saving emission reduction;(6) from P to H3PO4, the phosphorus and oxygen into water and phosphorus pentoxide, compound phosphate, the equation is P+O2=P2O5, P2O5+3H2O=2H3PO4,The answer is: P+O2=P2O5; P2O5+3H2O=2H3PO4

Landlord is a layman. First of all, correct your mistake, steel is not used coke, coke is used to iron. You can change the question, how much Coke refining 1 tons of iron

Q:The total amount of heat released by the fully burnt 200g coke is 60% by the mass of 10kg water absorption [q coke =3.0 * 107J/kg, C water =4.2 * 103J/ (kg = C)

At a standard atmospheric pressure, the boiling point is 100 DEG C, the temperature of the water rises to a temperature of 100 DEG C, and the temperature will not change,So the water temperature can be increased to 100;Answer: (1) the heat absorbed by water is 3.6 * 106J;(2) after absorbing heat, the temperature of the water will rise to about 100 degrees centigrade

Q:What are the requirements for coke and other accounts?

4, I personally set the password and password.5, the customer I own the bank transfer agreement, my ID card, bank debit card to the corresponding bank outlets for bank transfer procedures.6, the day of the day to accept the phone call Futures Company visit, after the successful return of T+1 days of commodity futures trading.7, the customer into the gold (silver period transfer; non bank transfer).8, customer online transactions (start trading).

Q:What is the essential difference between coal and coke?

Coke]Coke is bituminous coal in the absence of air is heated to 950-1050 DEG C, after drying, pyrolysis, melting, bonding, curing and contraction of the final stage is made, the process is called high temperature coking (high temperature carbonization). Coke obtained from high temperature coking for blast furnace smelting, casting and gasification. Coke oven gas produced in the process of coking and recovery is not only a high calorific value of fuel, but also an important industrial raw material for organic synthesis.Coke is mainly used in blast furnace ironmaking and smelting of non-ferrous metals such as copper, lead, zinc, titanium, antimony, mercury and so on. The use of coke instead of charcoal in the blast furnace has laid the foundation for the large-scale development of modern blast furnaces and is a major milestone in the history of metallurgy. In order to achieve better technical and economic indexes of blast furnace operation, the coke (metallurgical coke) must have proper chemical and physical properties. In addition to a large number of coke used in iron smelting and non-ferrous metal smelting (metallurgical coke), but also for casting, chemical, calcium carbide and iron alloy, the quality requirements are different. Such as foundry coke, generally require large size, low porosity, high fixed carbon and low sulfur; chemical gasification, strict requirements for strength, but requires good response, high ash melting point; calcium carbide and coke production requirements to improve the fixed carbon content.

Q:How coal is turned into coke in the coking chamber

Simply put is to let the coal in the isolated air furnace heating, volatile volatile, and the rest is cokeOf course, the volatile ingredients to be collected, are the baby
